Cov kua nplaum yas?

Ua ntej koj yuav nrhiav tau tawm yog dab tsi muab nplaum yas, nws yuav tsum tau muab sau tseg tias tag nrho cov yas, tsis hais txog ntawm polarity, ib txoj kev nto kev kho mob thiab cov tshuaj nyob tus yeees, yuav ntse sib raug zoo.

Piv txwv li, ib tug me nyuam txoj kev tawg qho khoom ua si, ua ib feem ntawm lub tsheb. Yuav kom sau tag nrho cov chaw nyob rau hauv uas lub ua ke ntawm yas siv, nws yog tsim nyog los tham txog tag nrho zus tau tej cov no cov ntaub ntawv uas.

Yas yog ib tug complex organic compound ua los ntawm polymers. Mus ua ib tug tsevneeg qhov chaw, tsuas yog zoo sib tov yuav tsum tau siv. Cov lag luam niaj hnub no muaj ib tug ntau ntawm cov nyiaj ntawm ntau hom mus xaiv haum adhesives rau yas, nws yog qhov zoo tshaj plaws mus tham nrog cob txhua tus neeg, thiab ua tib zoo xav txog cov ntaub ntawv nyob rau hauv cov lus qhia rau lub chaw.

Lub daim ntawv teev cov feem ntau nrov adhesives rau yas muaj xws li cov nram qab no cov khoom:

· Caij;

· Muaj zog Plast;

· Fais fab Plast;

· UHU;

· WEICON constraction;

· Nplaum AKFIX, thiab lwm tus neeg.

Cov kua nplaum yas: Lub tswv yim rau kev txhim kho qhov zoo ntawm cov kev twb kev txuas

Tej zaum yuav insufficiently check sib txuas ua ntawm txias curing adhesives. Ib tug tshwj xeeb tshaj yog tsis zoo rau ib tug cov ntaub ntawv uas, uas yog ua thaum muaj kev kub kub los yog cov pwm. Yuav kom txhim kho lub ua ke zoo thiab yog li nthuav lub ntau yam ntawm cov yas nplaum txhais tau hais tias pab cua kub txoj kev. Nyob rau hauv xws li mob, lub siab tshaj plaws compound peev xwm ua tau ib tug muaj zog epoxy thiab polyurethane nplaum yog zoo suited rau lub hom phiaj no thiab fenolopolivinilatsetalnye muaj pes tsawg leeg, e.g., BF, 0T, BC, BC-350.

Thermoset nplaum compositions yog glued zoo yas raws li yog thermoset polymers xws li polyurethanes, polyesters, epoxies thiab lwm yam ntaub ntawv. Rau cov yas yog haum, tsuas yog cov uas tau teev tseg tebchaw, furan thiab cyanoacrylate muaj pes tsawg leeg, raws li zoo raws li nplaum, uas muaj ib tug hluavtaws roj hmab.

Yuav kom zoo-versed nyob rau hauv lub qhov teeb meem ntawm yuav ua li muab yas, ib tug yuav tsum kuj paub tias qhov zoo ntawm cov kev twb kev txuas ntawm ib co thermoplastic ntaub ntawv yog zoo los ntawm kev siv ntawm ultrasound. Niaj hnub no tsim ib txoj kev los hloov polymeric chaw yuav tsum tau sib raug zoo los ntawm irradiation ntawm UV rays los yog halogens.

Cov kua nplaum yas: Cov lus qhia rau kev siv

Koj yuav tsum tau ua ntej kom paub tseeb tias qhov chaw yuav tsum tau kho huv si thiab qhuav. Lub npoo ntawm qhov chaw yuav tsum tau raws li meej tom rau txhua lwm yam. Tom ntej no, ib tug nplaum yog thov, koj yuav tsum tau kom paub tseeb tias cov softening ntawm seem ntawm nws yog nyob rau tag nrho cov chaw thiab ib tug tshaj plaws qhov tob. Nyob rau hauv chaw ua hauj lwm zoo siv ib tug txhuam hniav los yog ib tug syringe, tej zaum yuav siv lub sputtering txoj kev, los yog muaj ntaub ntawv los ntawm immersion cuab tam qhov chaw.

Ntxiv mus, los xyuas kom meej ib tug zoo zoo kev twb kev txuas, ob pos qhov chaw uas khaws cia nyob rau hauv siab, raug yuav tsum tau nqa tawm sufficiently thiab tsim ib tug nyuaj nplaum txheej. Tsuas yog tsis tau raws li siab tshaj plaws zog, nws tseem tau mus ua machining los yog finishing paub meej.

Cov kua nplaum yas, yuav ua li cas yuav ua rau nws, rau cov khoom tau kis thaum lub sij hawm lub lag luam? Yuav ua kom ib tug ruaj kev twb kev txuas yog feem ntau siv yas qhov cuab lub zog txoj kev siv ib tug tshwj xeeb cov khoom uas yog adhered los yog priplavlyayut kuab tshuaj los yog nplaum. Paub cov hom kev kawm compound thermoplastics los ntawm ntshav kev kho mob los yog los ntawm daim ntawv thov mus rau lub rhuab hlau nto txheej rau attrited hmoov loj (nyob rau hauv xws li mob, ib tug cam khwb cia hlau los yog hlau filings).

Yog hais tias koj tsis muaj peev xwm xam tau tawm raws nraim li cas hom ntawm cov yas nyob rau hauv pem hauv ntej ntawm koj yog ib qho zoo rau siv universal nplaum. Nws yog tsim rau cov kev twb kev txuas ntawm tej polymeric khoom, txawm li cas los, qhov zoo tshaj feem ntau nws qis tshaj li tus tshwj xeeb adhesives.
